A Model for Silmultaneous Optimization of Feeding Level and Slaughtering Policy of Organic Steers

نویسنده

چکیده

Organic steer production demand several decisions concerning grazing strategy, feeding level in the winter and factors as slaughter weight and length of the fattening period. The production can be difficult to optimise, therefore the objective of this study was to describe a model developed to optimise the fattening and slaughter strategy of steer production concerning economy at an individual level. The steer model is a 4level hierarchical Markov process with decisions defined at three levels. Decisions taken in the model include grazing strategy (marginal grass or clover grass), feed level in winter (high and low), time for beginning of fattening (19-27 months) and time of slaughter (19-30 months).

Effects of Alfalfa Particle Size on Ensalivation Rate, Chewing Efficiency, and Functional Specific Gravity of Particulate Matter in Hereford Steers

Six ruminally fistulated Hereford steers (body weight=414±13 kg) were used in a switch back design to determine whether two particle sizes of alfalfa hay (18.75 and 4.65 mm theoretical cut length) influenced salivary secretion during eating. The experiment carried out in two 26-d periods, with 11-d of adaptation to ration, followed by 5 d for determining the level of voluntary feed intake, 7-d ...

Effect of slaughter age and breed on the carcass traits and meat quality of beef steers finished on natural pastures in the ar

Simmentaler cross (SX), Bonsmara cross (BX) and Nguni (NG) steers were raised on natural sweet veld pastures and slaughtered at 18 or 30 months of age. Slaughtering occurred at the end of the wet summer season. Live weight and carcass traits were significantly influenced by breed and slaughter age. The amount as well as percentage kidney and omental fat differed significantly between the respec...

Developing optimal operating reservoir rule-curves in drought periods

In this study a simulation-optimization model is developed for deriving operation rule-curves in drought ‎periods. To each reservoir, two rule-curves with adjustable monthly levels are introduced dividing the ‎reservoir capacity into three zones between the normal water level and minimum operation level. To each ‎zone of a reservoir and for each month of the year a hedging coefficient is introd...
